UPDATE: T-Mobile USA restores service

T-Mobile USA Inc. reported late last night that it had restored voice and messaging services to customers hit by a network disruption.
The carrier posted on its Web site’s message board that on Tuesday evening about 5% of its customers were impacted by the outage in various locations across the country, and that by 10:25 pm Pacific Time services had been restored.
“Our sole focus has been restoring full services for all customers; we are now investigating the root cause of the incident,” the carrier noted in a posting by a message board moderator. “We sincerely apologize for the inconvenience that this has caused our customers.”
T-Mobile USA reported on its Twitter page Tuesday night that the carrier was experiencing a “service disruption” on its network and that it’s “rapid response teams have been mobilized to restore service as quickly as possible.” There were no details on the extent of the disruptions, though posts on its message boards seemed to indicate sporadic outages across the country for both voice and data services. The original Twitter posting from T-Mobile USA was made at 4 pm Pacific Time.
The network issues come on the heels of a melt down of the carrier’s Sidekick data services last month that temporarily cut off all users of its messaging-centric device to text and data services. Initial fears indicated that the Sidekick disruption included the loss of customer information stored on the devices and backed up on servers operated by Microsoft Corp., but most if not all of that data was eventually restored.
